When starting Z-Seer, I get a message that says "Unable to connect to HomeSeer, click OK to open the connection settings. This happens whether I run it on my HomeSeer computer or another computer on the network. On the HomeSeer computer, in the "Select System" dropdown, my HomeSeer IP address is listed but when I select it, I get the same error. On a different computer, I put in the IP of the HomeSeer system and I get that error. The message is very vague and doesn't give any information about WHY it's unable to connect.

Its a bug affecting some systems which HST never resolved. The only way to get it working is to put the Z-Seer.exe file in you Homeseer root folder and run it from there. Not very helpful if you want to run it on a remote PC.

I put it in that directory and it's still not working. I'm not getting that long error though. I'm getting the "Unable to connect". I'm sure it's something simple but I sure don't see it. I've attached a document with some screenshots.

Maybe I'm not putting the right thing in the "Host Name / IP Address" field. I've tried just the IP, the IP with the port (81) and localhost. Nothing works.

I was having the same communication problem and tried moving the EXE file with no success.

I decided to go ahead and register the software even though it was not working. During registration, I got a message telling me to update the plug-in. I found that I was not running the current version, so I updated. (Actually, after the update, I accidentally uninstalled the plug-in, and had to add it back.)

In any case, after all this, Z-Seer+ communicates properly with HS3 even with the EXE file located in its normal location.

This may or may not be what others are experiencing, but it solved the problem for me.

I have the same problem even after following all the advice above. I have 3.0.1.87: Z-Wave version.

You might try upgrading to the latest beta for z-wave which is .179. I am on .179 and it works there. Disable z-wave plugin first then upgrade then re-enable z-wave plugin. What version of HS3 are you on? I am on .368.
